  • Fig. 9 shows the turning bars 1 and 2 in a sweeping configuration.
  • this second new Configuration becomes a path half maximum width, or even smaller width, For example, one third of the width, on the side remote from the adjusting 20 side enters, by looping the upper turning bar 1 by 90 ° from the conveying direction F. the incoming web guided on a deflecting device, for example a Deflection roller, which is arranged on the side of the adjusting motors 20.
  • the diverted Web is wrapped around the bender in the turning bar floor 3 or 4 guided back and on the lower turning bar 2, the lower turning bar 2 wraps around and runs while maintaining the conveying direction F of the incoming web but with reversed top and bottom of the turning bar floor 3 or 4 off.
  • FIG. 10 The configuration of FIG. 10 is obtained from the configuration of FIG the upper turning bar 1 is simply offset parallel to itself while the lower turning bar 2 their assumed in the configuration of Fig. 3 position maintains.
  • the offset movement of the upper turning bar 1 is without unhooking the Turning bar 1 performed.
  • the parallel offset is thus solely by the Adjustment 19, 20 causes.
  • the second Turn bar holder 12 can not pinch in the displacement movement.
  • the Parallel displacement by means of the adjusting device 19, 20 could cause the relevant Turning bar 1, however, also released manually from the first turning bar holder 11a, then the first turner bar holder 11a by means of the adjusting device 19, 20 and the second turning bar holder 12 manually adjusted and finally the turning bar. 1 manually again with the first turning bar holder 11a in the new position get connected.
  • a parallel offset can thus either either a automatic / manual or fully automatic adjustment.
  • the fully automatic adjustment is preferred for the parallel offset.
  • the embodiment shows how by a combination of manual and automatic adjustment made by adjusting a simple and Therefore, inexpensive turner bar assembly can be created, compared to a purely manual folding the turning bars much more convenient and in less time can be configured. Setting up for a new production becomes too comparatively significantly reduced costs. A cost reduction could be achieved be replaced by a hand crank each of the adjusting motors 20. Such a However, purely manual solution can easily lead to a significant extension of the Redeploy required time, especially when setting up multiple Turning bars must be folded.
